Controlling Transmitter Output

2. The method of claim 1, wherein the pool of radio resources comprises resources at a plurality of different transmission frequencies.

4. The method of claim 3, wherein a controller that generates the control signal implements a proportional-derivative control scheme.

5. The method of claim 4, wherein the control signal comprises a first term which is proportional to the difference between the average output power and the output power reference value.

6. The method of claim 4, wherein the control signal comprises a second term which is proportional to a time-derivative of the average output power.

7. The method of claim 6, wherein the second term is restricted to values which are equal to or less than zero.

8. The method of claim 1, wherein the allocation of radio resources is set to a minimum value responsive to a determination that the average output power is within a proportional threshold of an output power maximum value.

9. The method of claim 1, wherein the average output power of the directional beam in the particular direction over a period of time is determined as a function of any one of an average total output power of the transmission point in all directions, a scheduled resource utilization parameter in the particular direction and a main lobe antenna gain, and one or more scheduled resource utilization parameters in directions other than the particular direction and a side lobe antenna gain.

10. The method of claim 9, wherein the average total output power of the transmission point in all directions is determined by measuring amplitudes of radio signals provided to the antenna array of the transmission point.

11. The method of claim 9, wherein the average total output power of the transmission point in all directions is determined by predicting the average total output power of the transmission point over a period of time.

14. The method of claim 13, wherein the second threshold value is greater than the first threshold value.

16. The network node of claim 15, wherein the allocated radio resources is a fraction of a total pool of available radio resources, and wherein the fraction varies as a function of the comparison between the average output power and the output power reference value.

17. The network node of claim 16, wherein the pool of radio resources comprises resources at a plurality of different transmission frequencies.

19. The non-transitory machine-readable storage medium of claim 18, wherein the allocated radio resources is a fraction of a total pool of available radio resources, and wherein the fraction varies as a function of the comparison between the average output power and the output power reference value.
